To call whom it may concern:

Be it known that 1, JAMES LEWIS AURAnD, a citizen of the United Statesof America residing in the city of Detroit, county 0 Wayne, State ofMichigan, have invented certain new and useful Improvements inanAutomobile Hood Lock; and declare the following to be a full, clear,and-exact description ofthe same, such as will enable-others skilled inthe art to which it pertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thesespecifications.

The object of my invention is to provide a lock which will attach tothe. folding wings of the hood inclosing the 'engineof an automobile, insucha manner as will enable the wings to be securely locked to the frameof the car, and prevent any tampering with the frame of, the car. i

Fig. 1, shows the back view of the lock' illustrating the generalconstruction, and operation of the working parts.

Fig.2, is a top view of the look as it is attached to the inner face ofthe automobile hood. Fig. 3, shows the look as it is attached to thehood wing of the automobile, and the means for operating and lockingsame to I will now describe more fully the detailed construction of thelock and the operation thereof, referring to the accompanying.

drawings and the marks thereon.

The operating-,mechanism is made in a. unit as shown 1n Fig. 1, andattached in about-the center of the lower inside face of the hood cover,as is shown in Fig. 3, and insuch. a manner that the operating handleprojects outside the hood, providing a means i I ets of'the supportingframe, which is usually for operating the lock bars connected thereto.-The lock-bars-eirtend to the ends of the hood cover and engage in thereceiving sockthe radiator at the front end'and the body of thecar' atthe rear end of the cover.

The mechanism of-thelock'is mounted on the plate 1 as shown in Fig. 1,said plate belng securely fastened to the lower inner surface of thehood. cover. portlon of plate l is a circular operatmg disc 1 whichissupported by a con- On the lower neeting shaft -3- passing through thebearing in the main plate 1. The disc 1s made to revolve in the bearingin either direction, and can be turned by means of the T handle 4.-- onthe outer end of the shaft -3. A stop notch is cut in the circumferenceon the lower edge of the disc,

and of a suflicient length to allow the disc to revolve a 90 degree turnin the main bearinga In the notch is a stop pin '5-- which is drivensecurely in the supporting plate -lin such a manner'that it engages thenotch in the operating disc and prevents only a partial revolutionthereof. 0n the upper half of the supporting plate 1 and securelyfastened thereto is a standard bolt lock 6, so arranged that the 'bolt 7can be operated to and from the disc 2-. The upper half of the disc isprovided with a notch to receive the lock bolt -7 when, turned by thekey -8, and whlch, prevents any rotatlon of the disc by any means. Oneach side of the operating disc .'2-- and hinged thereto, are horizon-.

tal lock-bars 9 extendingto the ends of the hood cover, and are guidedby the slide supports 10 which are fastened to the inner face of thecover near the outer ends. The lock bars --9 are free to slide in thesupports -10, and are supported by heavy springs ---11 Which areattached to the hood cover. in such a manner that the pressure againstthe lock bars will hold the cover down tight against the end supportsand prevent any rattle. The outer ends of the bars 9 are tapered onthe'top edges and engage the catches 1 2 and 1'3-- fastened to theradiator in the front and the body of the car at the rear end of thecover. Both catches are securely fastened to the supporting parts andare taperedon top to receive the ends of the lock bars and draw the hooddown tight when the bars are forced; in by the operating disc -.2- assame is turned by the T'handle The T handle may be used the same as theordinary lifting handle for opening the hood cover, but-when the cover.is down, by

turning the T handle a'qu'arter turn, the operating disc connectedthereto forces the-luck bars 9- into vthe sockets --12- and, l I

13- at the ends. of thehood cover, drawing the cover down tight over thehood supports, and is held firmly thereto by means of springs -11. Byturning the key -8- in the lock, the bolt v-7 engages the notch in theedge of the disc 2- and securely locks the cover to the radiator andbody supporttions.

I esser-*2 mg bars, means for supporting same on the cover of the hood,an operating disc mounted between the ends of the said bars andconnected thereto, means for operating said disc so. as to move the barsin and out of the V I sockets in the. hood supports, a tension springattached to the cover and operating against the lock bars to draw thecover firm-' 1y down against the supports, a lock bolt to prevent anyengage the operating discto rotation thereof when locked and means foroperating said lock. p
